[[quoteright:346:http://static.tvtropes.org/pmwiki/pub/images/821656-ultron__technovore__picture_3_8788.jpg]][[caption-width-right:346:"''CONSUUUUUUUUUUUUUUUUME!''"]]* Rhona tried to gas Whitney, cut Rhodey in half, vaporize Pepper and electrocute Happy.** And she did something similar once before, so she probably has quite the bodycount behind her.* Mallen, once he takes the Extremis formula. The creepy cocoon he comes out of, his black eyes with red irises, his decomposed skin, the growing insanity, not to mention his enhanced strength, super-speed, and lightning and heat powers, make him one of Iron Man's most terrifying foes.** There's also the sheer insanity in his actions.* Pretty much ''everything'' about Technovore. --> ''"Cooooooonsuuuuuuuume...!"''* MODOC itself is pretty scary. It's a technologically advanced Humpty Dumpty that, to put it simply, {{Mind Rape}}s you and steals everything in your head.** You didn't misread that, people. This show actually manages to make MODOC legitimately threatening.** Also, this version of MODOC looks [[UncannyValley just plain creepy]]. It's especially unsettling because because this was never a problem with MODOC.* [[spoiler:Justin]]'s beginning as Titanium Man has him brutally blow up Iron Man's empty armor, and actually express disappointment there are ''no blood splattering everywhere''.* Justin Hammer's zombie gas in ''The Hammer Falls'' and its effects. Also, Justin's VillainousBreakdown may qualify. [[AssholeVictim He deserves it]], but God is his SanitySlippage creepy.* Watching the Makluan Overlord's son being vaporized.* The extra-dimensional demon Dr. Doom summoned in his second appearance.* Magneto gets some credit for being able to find "Annie" no matter where she runs, claiming that he can sense the iron in her blood like a fingerprint. All in CreepyMonotone.----
